Hi, Ive hyperpro shocks installed a few weeks ago. I would like to adjust the preload and hight of the shock (option) However i cant seem to do it without taking the bike to the shop. I dont get it, how do you do it with the shock being on the bike. It seems impossibel. there is no space. r1200gs adv (2009) the hight setting is with a wrench on the bothem of the sock, i cant get the wrench in, the swingarm is it the way. the preload, i have to do with a special wrench after i loosen up a security bolt thing. Well i cant find the bolt. Anyone did this before who can help me a bit? can i take the rear shock off without taking it to a shop? Putting it on the centerstand and just wrench the top and bothem bolt of. or is there some sort of pretension that will snap my fingers off?
